Au niveau d’une extrémité avant, l’aile latérale du véhicule automobile est notamment découpée afin de pouvoir être pliée et de former un coin boule. Cette configuration permet ainsi de garantir une continuité de forme avec le pare-chocs avant du véhicule automobile et de faciliter l’assemblage du parechoc et de l’aile latérale sur le véhicule automobile. [3] In the prior art, motor vehicles are known comprising a junction surface between a front bumper, a side wing and a hood of the motor vehicle. The side wing of the motor vehicle is formed from a piece of metal sheet metal, shaped by stamping. At a front end, the side fender of the motor vehicle is notably cut so that it can be folded and form a ball corner. This configuration thus makes it possible to ensure continuity of shape with the front bumper of the motor vehicle and to facilitate the assembly of the bumper and the side fender on the motor vehicle.
[4] De manière connue, un joint d’étanchéité de capot est disposé le long d’une zone d’appui d’étanchéité qui s’étend en périphérie de l’aile latérale du véhicule automobile et du pare-chocs avant du véhicule automobile, au niveau d’un élément de structure du véhicule automobile qui délimite un compartiment moteur. Un tel joint d’étanchéité est configuré pour - une fois comprimé par la fermeture du capot - prendre appui contre la zone d’appui d’étanchéité afin d’assurer une isolation phonique du compartiment moteur situé sous le capot, limite les entrées d’eau et de débris dans ledit compartiment moteur et participe à l’aérodynamisme du véhicule automobile. [4] In known manner, a hood seal is disposed along a sealing bearing area which extends around the periphery of the side fender of the motor vehicle and of the front bumper of the vehicle. automobile, at the level of a structural element of the motor vehicle which delimits an engine compartment. Such a seal is configured to - once compressed by the closing of the bonnet - bear against the sealing bearing zone in order to ensure sound insulation of the engine compartment located under the bonnet, limit the entries of water and debris in said engine compartment and contributes to the aerodynamics of the motor vehicle.
[5] L’inconvénient de ces surfaces de jonction est qu’elles sont de forme complexe. La présence du coin boule sur l’aile latérale du véhicule automobile crée une interruption dans la zone d’appui d’étanchéité, autrement dit à l’interface aile latérale/capot. En d’autres termes, les contraintes d’usinage du coin boule qui nécessitent de réaliser un découpage de l’aile latérale à proximité de ce dernier conduisent à faire apparaître une ouverture non désirée au niveau d’un bord intérieur de l’aile latérale du véhicule automobile. Cette ouverture non désirée crée ainsi un défaut d’étanchéité qui laisse entrer l’eau et des débris dans le compartiment moteur du véhicule automobile. L’interruption dans la zone d’appui d’étanchéité est également préjudiciable pour le véhicule automobile d’un point de vue aérodynamique. Ce manque de continuité nuit aussi à la qualité perçue dudit véhicule automobile en termes de finitions. [5] The disadvantage of these junction surfaces is that they are complex in shape. The presence of the ball wedge on the side fender of the motor vehicle creates a interruption in the seal bearing zone, in other words at the side wing / bonnet interface. In other words, the machining constraints of the ball wedge which require cutting the side wing close to the latter lead to an unwanted opening appear at an inner edge of the side wing. of the motor vehicle. This unwanted opening thus creates a sealing defect which allows water and debris to enter the engine compartment of the motor vehicle. The interruption in the sealing bearing zone is also detrimental for the motor vehicle from an aerodynamic point of view. This lack of continuity also harms the perceived quality of said motor vehicle in terms of finishes.
[6] La présente invention a pour objet de proposer un nouveau pare-chocs avant de véhicule automobile afin de répondre au moins en grande partie aux problèmes précédents et de conduire en outre à d’autres avantages. [6] The object of the present invention is to provide a novel motor vehicle front bumper in order to at least largely meet the above problems and further lead to other advantages.

[13] Le rebord intérieur d’appui est destiné à être situé du côté d’un compartiment moteur du véhicule automobile avec lequel le pare-chocs avant est destiné à collaborer. En ce sens, le rebord intérieur d’appui est « intérieur » au véhicule automobile. [13] The inner support rim is intended to be located on the side of an engine compartment of the motor vehicle with which the front bumper is intended to collaborate. In this sense, the inner support rim is "inside" the motor vehicle.
[14] Chaque élément de carénage latéral est destiné à être positionné sur l’un des flancs du véhicule automobile équipé du pare-chocs avant conforme au premier aspect de l’invention. [14] Each side fairing element is intended to be positioned on one of the sides of the motor vehicle equipped with the front bumper according to the first aspect of the invention.

[17] The front edge of the fender is intended to face the front of the motor vehicle equipped with the front bumper according to the first aspect of the invention, facing the rear edge of the side fairing element.
[18] Le joint associé au capot est destiné à être écrasé contre le rebord intérieur d’appui de l’élément de carénage latéral et contre la languette de l’élément de carénage latéral lorsque le capot est fermé. Une certaine étanchéité du compartiment moteur logé sous le capot est ainsi garantie. [18] The seal associated with the cover is intended to be crushed against the inner bearing edge of the side fairing element and against the tongue of the side fairing when the hood is closed. A certain tightness of the engine compartment housed under the hood is thus guaranteed.
[19] Le capot associé au joint avec lequel le pare-chocs avant est destiné à collaborer est un capot avant du véhicule automobile. [19] The hood associated with the seal with which the front bumper is intended to collaborate is a front hood of the motor vehicle.
[20] Le rebord intérieur d’appui de l’élément de carénage latéral et la languette de l’élément de carénage latéral sont configurés pour collaborer avec le joint associé au capot du véhicule automobile. Notamment, lorsque le capot du véhicule automobile est fermé, le joint est écrasé entre le capot du véhicule automobile et le rebord intérieur d’appui de l’élément de carénage latéral d’une part, et entre le capot du véhicule automobile et la languette de l’élément de carénage latéral d’autre part. Plus précisément, l’appui du joint contre l’élément de carénage latéral et contre la languette prend la forme d’un appui latéral, orienté depuis le compartiment moteur et en direction de l’aile latérale. Il ne s’agit pas ici d’un appui vertical, orienté depuis le capot et vers le bas. [20] The inner supporting rim of the side fairing member and the tongue of the side fairing member are configured to collaborate with the seal associated with the hood of the motor vehicle. In particular, when the hood of the motor vehicle is closed, the seal is crushed between the hood of the motor vehicle and the inner bearing flange of the side fairing element on the one hand, and between the hood of the motor vehicle and the tongue. of the side fairing element on the other hand. More specifically, the support of the seal against the side fairing member and against the tongue takes the form of a lateral support, oriented from the engine compartment and towards the side fender. This is not a vertical support, facing from the hood and down.

Un exemple de moyen de fixation détachable est par encliquetage. Un exemple de moyen de fixation non détachable est par exemple par collage. [34] - according to a first variant embodiment, the tongue is made from material with the front bumper. The term "made from material" is understood to mean the fact that, in the front bumper according to the first aspect of the invention , the tongue and the front bumper cannot be separated from each other without damaging all or part of their integrity. Thus, in the front bumper according to the invention, the tongue and the front bumper form an assembly referred to as a single piece due to the fact that together they form only one and the same continuous part, made in one piece. and obtained during the same process of manufacturing. The invention in accordance with its first aspect thus advantageously makes it possible to obtain a prefabricated front bumper, the manufacture of which is simplified since it does away with the assembly of the tongue as well as the presence of fixing means of the tongue. In addition, a one-piece front bumper can be machined into a variety of different sizes so as to be suitable for different models of motor vehicles. Such a front bumper is also more rigid and lighter. According to a second alternative embodiment to the first alternative embodiment, the tongue is attached to the front bumper, by fixing means, detachable or not. An example of a detachable fastening means is by snapping. An example of a non-detachable fixing means is, for example, by gluing.
